The Tumbler is the most badass Batmobile ever (it's a freakin' tank), but what if it was a Transformer? This is definitely what it would look like: A Decepticon-shredder. Bat-ingenuity, Transformer tech and sheer badassery definitely make this the beastliest 'bot out of Cybertron. Optimus Prime had better watch his back. I want one.
